Which are examples of water absorbing energy? When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation. Water vapor (steam) mixes with the air and seems to disappear. A simple example is water boiling in a teapot and escaping into the air. What happens when the kinetic energy of […]

How can you increase the density of air?
How can you increase the density of air? Density and pressure/temperature As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases. Air density will decrease by about 1% for a decrease of 10 hPa in pressure or 3 °C increase in temperature. What factors affect air density? Pressure, […]
Can AC run DC?
Can AC run DC? You can use AC coils on DC circuits providing you apply enough DC voltage to draw the same amount of current as when operating on AC. Here’s an alternative to rewinding AC coils so that they can operate on DC circuits. It’s a relatively simple procedure requiring some calculations and some […]
